I'm unable to link to it, I allways get this error message (tried a few times over the last days as I hoped it might be a temporary problem):

The Username/EMail combination does not seem to exist on Hacking-Challenges.

Anyone hav an idea?

Unfortunately there is not much activity and most Challengers seem not to interact through the forum or pm. I'm trying to ask here if someone has solved Category: JavaScript, Chall: ACCESS DENIED!!! 'cause I got it, but it's not accepted. Haijo18 tried to explain the typo in the forum, but it doesn't make sense. Btw I know German.
If yes, may I contact someone? Thx in advance.

<EDIT>Btw, pretty sure I got the correct answer also to that one Category: JavaScript, Chall: Members-Only Area! Sad

SideNote: tried to contact C-tecx in 2019 for another chall's typo. Also guybrush1112 for another chall in 2020...

Hi Occasus,

I agree with you that the community doesn’t seem to be very active, which can make it harder to find quick answers or discussions. However, regarding this specific challenge, I think the help provided in the forum is actually quite clear and easy to understand—especially if you already found part of the solution. If you need to compare your approach or discuss it further, feel free to contact me privately.
